Iphone 3G unlocked testing
I want to check my iphone 3G (my old iphone) has been unlocked by o2, but I don't want to lose everything on my old iphone as it is used for my alarm etc (sits in my docking point, unlike my iphone5!).
If I "Erase All Content and Settings" and test the unlock, will I then be able to go back to itunes and put my old data (that is now also on my iphone5) back onto the phone?
Thanks
Dom
p.s. I'm going off this advice re unlocking:
